To all whom tmay concern: 4

t l' Be' it known that I, WILLIAM GOLD'I-NG, of

New Orleans, in theparsh of Orleans and State ot' Louisiana, have invented a new and Improved Trunk-Engine; and I do hereby declare l that thcfollowing is afull, clear, and exaetde-l scription` thereof, which will enable others` skilled in the art to make and use the same,

reference 4bei n g had to the accompanying drawings, forming a part ofthis' specification, 'in `Whichv Figure l represents a'vertical central section of this invention. Fig. 2 is a detached plan ot' theradius-arni, which isafpplied. 4to limit the vibrations ofthe cross-head, lFig. 3 is adetached `sectional view of the trunk and its connections.

Similar letters' of' reference indicate like This invention consists inthe application of4 a .radius-arm, in combination with the connect:-v ingrod, erossfhead, and link connecting said crossLhead withthe trunk ot' a' trunk-'engine in such a inannerfthat bythe action of said ra-i ldusarm the vibration of the link in the trunk isdiminished, and the diameter ot' saidtrunk lcan be considerably reduced, and .at the same time the trnnk is relieved of the .friction and the cutting liable fromjthe pressure of the conrests on'eolumns AC, as clearly shownin the 4drawings,.or` it may-be put up in any other con- Figs. 1 andi; ofthe drawings, and its outer end `is forked, 's olthatp it straddles .the'end of .the

oonnecting-rod,as shown'in Fig.3 yor the coni nection betweenthelinkandtrunk on one and A the link and connecting" rod on the opposite end of said llink may be e'ected 'in' any other desirable'manner.v .The'f connecting f rodxbvv ex-` ,tends from the cross-head'to the cccen tric wrist-q pin c', vwhich lis secured' in' the linkl or crank 4d lin the usual manner; and 'in order to shorten the vibrations of the crossihea'd I have applied a radius-arm, G, lwhich is secured to the rock` i shaft e, that has its bearings in suitable brack-I ets, i f, on the side or underthe 'platform B. vSaid',

radius-arm is either made with a fcnked.end, V 4or in two parts, which straddle the forked end ot' the link Fand connect to the cross-head in-V any desirable manner, 'and by its'action the vibrations of the 'cross-head. are limited to the are described by the loose end ot'. the radius; arm. The radins-arm sustainsthe entire `lat@ eralA pressure ot' theconnection-rod,'and the-di' ameter'of the trunk can be reducedfnlly, one# half;V and, furthermore, said trunk is relieved from alllateral pressure and 'preserved from the cutting aris'i'ngfromthe pressure of theconnectingjrod. t Y Havin g thus described my invention, 1 claixn as new and desire to secureby Letters Patent- The radins armG, applied, in combination with the connecting-rod b, cross-head a, link E,

` and trunk E; substantially inthe manner an'd for the purposexhereinshownand described.-
